okay i got an axle now and im not positive but i read some where that from 73-80 4.10 gears and up have limited slip(gov lock whatever) and 81-up 4.56 gears and up have limited slip? i have a 14b ff 4.10 from January of 76 so what should it have?
also i am swapping this into my 95 k1500 so i know i have to move the spring perches from 42.5" to 46" or 47" what ever it is but when i weld the new ones on should i keep the same pinion angle or change it
last but not least the u-joint, should i get a 1350 series(which is for the 14 b) and just use two caps from my 1310 series(from my 10 bolt) so i can use my stock drive shaft?

First, pull the diff cover off and look, a govloc will have a bunch of extra parts inside.

Second, with a non-cv driveshaft match the t-case output angle with the rear diff pinion angle.

You're probably better off using a conversion joint of some sort. I've never dealt with them really but I don't think putting used caps on a new U-joint is a good Idea. Try calling the Auto Zone in Fenton and ask for Jim. He's a u-joint expert. He will probably know what the part number is to the U-joint you will need to make it work.

As far a pinion angle, if you don't have a cv shaft the angle of the joint on the axle and the angle of the joint on the t-case or trans should be the same for best results.

hey guys i gotta question for ya. i got a 78 ford with a dana 44 straight axle up front and a gm 14 in the back both with 410 gears welded. is there any way i can make the rear 8 lug a 5 bolt 5.5 to fit my old rims?
